Frequently Asked Questions

What is Verimail?

Verimail is a bulk verification tool and REST API that verifies email addresses. For every email address you provide we will perform multiple checks and tell you if it is safe to send emails to this address or not.

Why do I need to verify my mailing-list?

Sending emails to unreachable mailboxes will hurt your delivery rate. If over 10% of your emails are undeliverable, then less than 44% are delivered. It is best practice to clean-up your mailing-list at least once a year.

How reliable is it?

We guarantee 99% deliverability on the emails we return as deliverable. On the technical side, Verimail runs on Google's cloud platform, with an SLA of 99.95% and scalable to thousands of requests per second.

Do I need technical skills to use Verimail?

No. Bulk validation is as easy as 1,2,3: Upload your CSV, validate, download. If you need real-time validation using our API, contact us, we can help with the technical setup.
